Abstract
Toy water guns include a housing supporting a liquid storage chamber, a conduit for establishing fluid communication between the chamber and a discharge orifice disposed proximate a front end of the housing, a trigger mechanism, a fluid transfer system adapted to develop forces for causing a continuous or pulsed stream of liquid to flow through the conduit and out of the discharge orifice when the trigger is pressed. A first embodiment employs a rotatable nozzle assembly that is dimensioned and arranged to spin as it receives a stream of liquid via the conduit. The nozzle assembly ejects a stream of liquid as it spins to thereby obtain a helical “tornado” flow pattern. In a second embodiment, a fixed or movable deflector is used so that water exiting a nozzle strikes a surface of the deflector to thereby develop a “wave” or “hard rain” discharge pattern. Multiple modes of operation are also contemplated.
